Abstract
A hub assembly for a bicycle includes a hub shell, a plurality of pawl units, and an annular ratchet member. The hub shell is rotatably mounted on a hub axle, and the annular ratchet member is disposed to rotate with respect to the hub axle. Each pawl unit includes a pawl that is movable between driven and idle positions, an elongated mount that extends to bridge a gap formed in the pawl, and a biasing member that is mounted on the elongated mount to bias the pawl to move to the driven position so as to engage to the annular ratchet member.
